Researchers have developed an implant made from pig’s skin which resembles the human cornea and can restore sight to the blind and visually impaired, according to a study.
In a pilot study, the implant – made from collagen protein from the animal – restored vision to 20 people with diseased corneas, most of whom were blind prior to receiving the implant.
